In this lesson, students will learn how cosmic rays were discovered and what they are - including their size and speed. Includes background information for the teacher, questions, activities and information about student preconceptions. This is...(View More) lesson 1 of 4 from "The Cosmic Ray Telescope for the Effects of Radiation (CRaTER)."(View Less)

This is a unit in 7-8 sessions about objects outside of our solar system, including galaxies and the universe. Learners will investigate the contents of the universe, why light years are used to measure distances in space, the lifespan of a star,...(View More) and detecting extrasolar planets. Finally, they will examine evidence for habitable worlds beyond earth. This is Unit 4 of the GEMS Space Science Sequence for Grades 6-8, which is available for purchase (see related link).(View Less)

Learners will construct a model to show the relative size and scale of the Sun-Earth system, investigate the visible and electromagnetic spectrums, discuss solar flares and solar weather, develop a UV shield, and discuss the results of their...(View More) investigations. The unit is set in the context of solving a mystery and supports the idea that scientific explanations are based on evidence. This is Unit 1 of the GEMS Space Science Sequence for Grades 6-8, which is available for purchase (see related link).(View Less)

This is an activity about the magnetic fields of the Sun and Earth, and the interplanetary magnetic field, or IMF. Learners will engage in a question and answer dialogue, make connections using bar magnet examples and overhead transparencies, and...(View More) ultimately write an assessment of concepts learned. This is Activity 1 in Session 3 of the Exploring Magnetism in the Solar Wind teachers guide.(View Less)

This is a lesson about magnetism in solar flares. Learners will map magnetic fields around bar magnets and investigate how this configuration relates to magnetic fields of sunspots. This activity requires compasses, bar magnets, and a equipment for...(View More) the instructor to project a PowerPoint or pdf lecture presentation.
